About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-30S
The AirTAC SAIJ80X230-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from the 230 mm nominal stroke to a 200-230 mm window. Delivering a robust 3518 N push force at 0.7 MPa, it is built with a SUS420J2 stainless steel rod (A option) for superior corrosion resistance and a 25 mm rod diameter paired with an M20x1.5 thread to handle high side loads.
This unit includes a magnet (-S) for position sensing, operating seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted into the extruded aluminum barrel sensor grooves. It uses PT tapered port threads (G3/8) and relies on variable air cushions at both ends to decelerate the moving load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-30S Is Used
Product Changeover
Dial in the end-stop within the 200-230 mm window during packaging line size changes without disassembling the actuator.
End-Position Tuning
Fine-tune the retract stroke at machine commissioning to perfect the pressing or clamping position.
Sensor-Driven Positioning
Leverage the internal magnet with DMSE electronic sensors to confirm travel across the adjusted stroke window.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-30S the Right Cylinder?
Choose this 80 mm bore when an application requires more thrust than the 63 mm bore (which provides 2182 N push at 0.5 MPa) but less bulk than the 100 mm class. The adjustable stroke is ideal for machine setup and product changeover, allowing you to dial in the exact end-of-stroke position within the 200-230 mm range without swapping cylinders or adding external stops. Because the stroke is 230 mm, ensure an external guide is used if the load is heavy or unsupported to prevent excessive rod side-loading.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, select the SAIL or BSAI series instead. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-30S FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder provides 3518 N of push force and 3518 N of pull force. It can deliver up to 4523 N push force at 0.9 MPa.
The rear external stopper screw lets you shorten the 230 mm nominal stroke by up to 30 mm, creating a usable travel window of 200-230 mm. The adjuster sets the end position but does not lock the load without continuous air pressure.
